In bufiing the action is similar, except that thestrain is transmitted through the block 7 directly to one of thefollowerplates, while the other follower-plate engages the stop-lugs orabutments 4:, the slots 8 be ing long enough to allow a sufficient freemovement of the ends of the straps.

Heretofore it has been the practice to employ two sets of draft andbuffing mechanism on a car, one set being placed at each end; but bymeans of my improved connections a single mechanism of this type may beutilized to take up the shocks and resist the strains due to draft andbufiing from either or both ends of the car, thus saving great expensein the equipment.

Having now described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In a draw-gear and buffing apparatus, the combination with thedraw-heads and a yielding draft and bufling mechanism for transmittingstresses to the car-frame, of intermediate independent connectionsadapted to transmit the draft and bufling strains from either end of thecar to said draft and buffing mechanism.

2. In adraw-gear and buffingapparatus for cars, the combination with adraw-head at each end of the car and a yielding resistance mechanism fortransmitting stresses to the car-frame, of independent means connectingeach draw-head with the yielding resistance mechanism and adapted totransmit draft and bufling strains from either end of the car axially tosaid mechanism.

3. In a draw-gear and buffing apparatus, the combination with a yieldingresistance mechanism and follower-plates for transmitting stresses tothe car-frame, of a draw-bar at each end of the car and an independentconnection from each draw-bar engaging one of the follower-plates.

4:. The combination on a car, of a yielding resistance member,follower-plates therefor,

a draw-bar at each end of the car and a strap secured to each draw-barand passing around the follower-plates.

5. In a draw-gear, the combination with a draw-bar at each end of thecar and a yielding resistance mechanism for transmitting stresses to thecar-frame, of independent means connecting each draw-bar with theyielding resistance mechanism and adapted to transmit draft strains fromeither draw-bar to said mechanism.

6. In a draw-gear, the combination of a yielding resistance member, adraw-bar at each end of the car, and a strap secured to each draw-bar,each strap passing through the other and around the yielding resistancemember.

7. In a draw-gear, the combination of a yielding resistance member, adraw-bar at each end of the car, and a strap secured to each draw-barand passing around the yielding resistance member, the plane of eachstrap being inclined to the vertical.

8. In a draw-gear, the combination with a draw-barat each end of thecar, a yielding re sistance mechanism and follower-plates therefor, ofslotted buiiing-blocks connected to the draw-bars for engaging thefollower-plates, and a strap secured to each draw-bar and extending intothe slot of the opposite bufiingblock.

9. In a draw-gear, the combination with a draw-bar at each end of thecar, a yielding re sistance mechanism, and means for transmitting thedraft and bufling stresses from the yielding resistance mechanism to thecarframe, of independent means connecting each draw-bar with theyielding resistance mechanism and adapted to transmit stresses fromeither draw-bar to said mechanism.

10. In a draw-gear, the combination with abutments secured to thecar-frame, followerplates engaging said abutments, and a yieldingresistance mechanism located between the follower-plates, of a draw-barat each end of the car, and independent means connecting each draw-barwith the yielding resistance mechanism and adapted to transmit stressesfrom either draw-bar to said mechanism.

In testimony whereof I have hereunto set my hand.
